This paper describes 2×2 MIMO 802.11ac Stage 1 WiFi + BT combo SoC chip with integrated dualband PAs, LNAs, T/R switches, as well as a power management unit. The measured RX sensitivity of OFDM54M is −77.5dBm/ −77dBm in 2.4GHz and 5GHz, respectively. With the proposed broadband TX architecture, a high output power of 17.5dBm for 802.11ac Stage 1 VHT80 256QAM was achieved, and is extendable to the...
A highly integrated WiFi/BT/FM/GPS connectivity combo SOC is implemented in a 60nm CMOS process. This work presents the proposed WiFi/BT merged RF transceiver, a virtual SP3T switch, and DPD algorithm to save chip area, reduce BOM and enhance performance simultaneously. The WiFi/BT/FM/GPS RF transceiver areas are l.7/l.3/0.8/l.0mm2, respectively. The measured WiFi 11g 54Mbps RX sensitivity is −78dBm...
